Symbols Table (Custom OFDM)

Trace > Data > Stream X > Ch(x) > Symbols

where X is the selected input channel and Stream

Symbols table lists the demodulated symbols and state values transmitted in the OFDM burst including Preamble and Payload symbols.

Trace Color coding Scheme

A multi-color coding scheme is used to make it easy to visually identify common symbols, subcarriers, and data results within various OFDM Traces. This makes cross trace data comparisons and analysis easy to accomplish. Different colors are assigned to symbols representing a common subcarrier type including: Preamble, Pilot, Data, and Null subcarrier types. Some common color scheme Traces include: Error Vector Spectrum, Error Vector Time, IQ Meas, OFDM Data Burst Info, and Symbols trace data.

You can also customize and re-assign Trace colors schemes, see the Display Preferences Color tab (click Utilities > Display Preferences > Color tab and select a new color for the active Mod Type element).

Limiting Symbol Analysis Region

You can use the Measurement Interval and Measurement Offset properties to limit measurement analysis to a specific symbol or range of symbols (Measetup > CustomOFDM Demod Properties > Time tab).
